Document Summary
First century of modern genetics: gregor mendel published explanation of hereditary transmission in plants in 1866, his work was ignored, but then independently rediscovered in 1900 by 3 botanists: correns, de vries, and von tschermak. Genes and chromosomes: genes: are the physical units of heredity, originally postulated by. Mendel, not known to be defined dna sequences: chromosomes: are long molecules of double-stranded dna and protein, which contains genes, compacting the dna is crucial, sexually reproducing organisms usually have homologous pairs (homologs), two of each chromosome. Double helix of dna wrapped around proteins called histones, this histone. Dna complex is known as a nucleosome, these form chromatin, and is then packed super tight. Turner"s(xo) viable female but cant produce functional eggs, kleinfelter"s, super male(2-y) What purpose does compaction serve: protects it/ more stable, more easy to manipulate and reduces mistakes during transcription.
